(57) The present invention relates to an acid gas absorbing mixture and a process for the removal of acid gases (sour gases according to the most widely used terminology) from gaseous mixtures containing them, such as natural gas, air and flue gases. More particularly, the invention relates to an absorbent mixture usable for the removal of acid gases from gaseous mixtures containing them, comprising: C) at least one diol of general formula R(OH) 2 having a normal boiling point equal to or greater than 100°C, wherein R is an alkyl group, linear or branched, possibly substituted, having a number of carbon atoms comprised between 2 and 8; D) at least one organic base having a pKb (in water) lower than or equal to 3; C) a polar aprotic solvent having a dielectric constant e at 25 °C greater than or equal to 30, a viscosity |i at 25 °C lower than or equal to 40 cP (centipoise), preferably lower than or equal to 20 cP, and a normal boiling point equal to or greater than 140°C, and wherein the organic base/diol weight ratio is lower than or equal to 0.6 and preferably greater than or equal to 0.25, - the aprotic solvent/diol weight ratio is comprised between 0.05 and 0.6. ________________________________________ (11) 21662 Consulter le mémoire (51) F25J 3/00 (2018.01) (21) 1202300198 - PCT/EP2021/082545 (22) 22/11/2021 (30) DE n° 10 2020 130 946.5 du 23/11/2020 (54) Cryogenic Process For Obtaining Product Of Value From A Hydrogen-Rich Input Gas.
